Show me proof from that article that photons travel at less than c

Dude...it's right in the first paragraph

"For example, the refractive index of water is 1.33, meaning that light travels 1.33 times slower in water than it does in vacuum."

Unless you're trying to say photons aren't light? 

Yeah that's saying the group velocity of light waves is slower in a bulk material. Not the same thing at all.
